Application February 14, 1955, Serial No. 487,792

I 1 Claim. c1. 292-34118) This invention relates to improvements in closure mechanisms and more particularly to novel concepts in strike plate assemblies as are used on door closure mechanisms and the like.

The primary object of the present invention resides in the provision of an adjustable strike plate assembly wherein the latch receiving openings in the strike plate may be both vertically and horizontally adjusted by means of a simple mechanism.

The construction of this invention features a strike plate having apertures therein and also spaced notches in the strike plate communicating with the apertures and extending around the periphery thereof. A securing plate of suitable configuration is so positioned as to be engaged in selected of the notches and being rotatable about a fastener so that the strike plate may be readily adjusted both vertically and horizontally by movement of the securing plate from one position to another without removing the fastener from a door frame or the like, the fastener holding the securing plate to the door frame.

Another form of the invention features the use of rows of holes in the strike plate and rows of pins on a securing plate with the securing plate being rotatable about a fastener so as to be capable of being moved from one position to another.

A further object of the invention resides in the provision of a strike plate assembly including a strike plate and means for easily adjusting the strike plate to various positions.

Still further objects and features of this invention reside in the provision of a novel strike plate assembly that is simple in construction, highly eflicient in operation, strong and durable, and relatively inexpensive to manufacture, thereby permitting wide use and distribution.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this strike plate assembly, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a perspective view illustrating a strike plate assembly constructed in accordance with the concepts of this invention as operatively installed;

Figures 2 through 5 are plan views illustrating a portion of the strike plate assembly in various adjusted positions;

Figure 15 is a perspective view of one of the securing plates.

With continuing reference to the accompanying draw ings wherein like reference numerals designate similar parts throughout the various views, and with initial attention directed to the embodiment of the invention as is shown in Figures 1 through 7, it will be noted that herein there is disclosed a strike plate assembly generally designated by reference numeral 10 which is adapted to be secured to the door frame 12 or other suitable closure housing. The stn'ke plate assembly 10 is provided so as to make it much easier to install new locks and so as to eliminate high skill for the installation thereof since this construction allows adjustment for error. Further, the strike plate assembly 10 permits adjustment for sagging doors caused by warping or wearing of hinges and permits adjustment to be made due to wear of the lock itself or of the strike plate.

The strike plate assembly 10 includes a strike plate 14 having openings as at 16 and 18 therethrough of any desired configuration for reception of the latching mechanism of the door lock. There are also provided a pair of apertures 20 and 22 in the strike plate 14. The apertures 20 and 22 are in communication with and have spaced about the periphery thereof suitable notches, as at 24 and 26, the notches being substantially rectangular and being shaped to form bevel surfaces, as at 28 and 29.

Securing plates 30 and 32 of identical configuration are provided, and these securing plates 30 and 32 are generally of a square shape having rectangular projections 34 and 36 extending about the periphery thereof with the projections 34 and 36 having bevel surfaces 38 complementary to the bevel surfaces 28 and 29 formed by the notches 24 and 26. The securing plates 30 and 32 can thus be secured readily within the apertures 20 and 22 and flush with the strike plate 14. The securing plates 30 and 32 have holes, as at 40, therethrough. The holes 40 may be counterbored for reception of the screw fas-- teners or other type securing means, as indicated at 42 and 44, which extend through the holes 40. The holes 40 are eccentrically positioned with respect to the center of the securing plates 30 and 32, and this offset permits the securing plates 30 and 32 to be rotated to the various positions, as is shown in Figures 2, 3, 4 and 5; with the projections 34 and 36 being engaged in different of thenotches 28 and 29, the rotation of the securing plates 30 and 32 being sufficient to vertically adjust the strike plate 14 while the interlock between the projections and the strike plate in the notches serves to horizontally adjust the strike plate. Of course, the securing plate fastening screws 42 and 44 are loosened prior to rotation of the securing plates. The bevel surfaces on the strike plate 14 and the securing plates 30 and 32 serve to ensure proper anchoring of the strike plate 14.

Referring now to the embodiment of the invention as is shown in Figure 8, herein there is shown a portion of a strike plate assembly 50 which includes an aperture 52 having spaced notches 54 extending about the periphery thereof and being formed with bevel surfaces as at 56. Securing plates, as at 58, are provided and held in place by means of fasteners 60 which extend through suitable apertures offset from the center of the securing plate 58.

As can be readily observed, the rotation of the securing plate 58 will serve to both vertically and horizontally adjust the strike plate 50 with great sensitivity, and the bevel surfaces, not shown, formed on the securing plates 58 which cooperate with the bevel surfaces 56 will ensure that the strike plate 50 is held in proper position.

Referring now to the embodiment of the invention as is shown in Figure 9, herein there is disclosed a strike plate assembly generally designated by reference numeral 70 which includes a, strike plate 72 having channel portions 74 and 76, each of which is provided with apertures, as at 78 and 80 therethrough. Further, the central portion of the strike plate 72 is provided with openings 82 and 84 for reception of the latch mechanism of the lock with which the strike plate assembly 70 is associated. Rows of apertures, as at86 and 88, are formed in the channel sections 74 and 76 of the strike plate 72 above and below the apertures 78 and 80.

A pair of securing plates and 92 are provided, and these securing plates have apertures as at 94 therethrough for reception of securing screws or fasteners as and 98 which extend through the apertures 78 and St) to hold the securing plates 99 and 92 to the door frame or other portion of the closure with which the strike plate assembly 70 is associated. Since rows of pins, such as are indicated at 169, see Figure 15, are appended to or integrally formed with the securing plates 90 and 92, the screws 96 and 98 will serve to hold the strike plate 72 in an adjusted position since the pins 100 will be adjnstably positioned within selected of the rows of apertures 86 and 88. By loosening the screws 96 and then rotating the securing plates 90 and 92, different positions in vertical as well as horizontal adjustment of the strike plate 72 can be accomplished.

The securing plates 90 and 92 seat in the channel portions 74 and '76 and lie flush with the outer surface of the strike plate 72. The strike plate can be adjusted to attain any of the various positions shown in Figures 10 through 13. I

The foregoing is considered as illustrative only of the principles of the invention, Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation as shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

An adjustable strike plate assembly for a door lock comprising a strike plate having at least one opening therethrough for reception of a latch mechanism, said strike plate having at least one aperture therethrough, said strike plate having a portion thereof having a plurality of rows of holes therein adjacent said opening, a securing plate of smaller dimensions than said portion of said strike plate, said securing plate having a plurality of rows of pins appended thereto and extending normal thereto, said pins being selectively extensible into said rows of 'holes, said securing plate being vertically and horizontally adjustable relative to said strike plate, said securing plate having a hole therethrough, and a fastener extending through said hole in said securing plate, said hole in said securing plate being offset from the center of said securing plate.
